How to Delete a User Account From a Trusted Extensions System

When a user is removed from the system, you must ensure that the user's
home directory and any objects that the user owns are also deleted. As an
alternative to deleting objects that are owned by the user, you might change
the ownership of these objects to a valid user.

You must also ensure that all batch jobs that are associated with the
user are also deleted. No objects or processes belonging to a removed user
can remain on the system.
